Unlike the single-family residential market where a one-size-fits-most approach to HPWH systems is feasible, multifamily water heating systems require more varied designs targeted at specific building types and sizes. Design possibilities are myriad, beyond mere equipment selection, but many...

This document is a report on the Southern California Edison (SCE) Codes and Standards (C&S) Planning and Coordination (P&C) subprogram key initiatives for 2023.  The P&C subprogram aims to support California's energy transition and decarbonization goals by coordinating and...

This Flexible Load Technical Potential project is exploring the expected growth in electrification technologies and estimating the effect on residential, small commercial, and medium commercial customer load profiles as well as estimating the technical potential of flexible load as these load...

The California Investor-Owned Utilities (CA IOUs) analyzed validated datasets of performance data for electric pumps, motors, and compressors collected as part of Measurement and Verification (M&V) of custom incentive programs for these types of equipment commissioned by the California Public...

As part of their Sustainability Strategy and commitment to reach net zero greenhouse gas (GHG) emissions by 2045, SDG&E launched a Virtual Power Plant (VPP) Project in 2021. The VPP was an initiative to strengthen community resilience and electric reliability in the unincorporated community of...

The Emerging Technologies Program at SDG&E chose The Energy Smiths to evaluate the electrical load and demand response capabilities of two (2) types of Atmospheric Water Generators, also known as dehumidification drinking water systems. These systems both generate drinking water by...

The successful implementation of solar photovoltaic in California has resulted in a monumental shift of our daily grid net demand profile. So much so, that net demand dips well below historic usage profiles and has shifted our peak demand period from the middle of the day to the evening hours (4:00...

Domestic hot water system electrification is a high-potential decarbonization opportunity in multifamily buildings. Based on U.S. government data, this end use accounts for 28% of multifamily residential energy consumption in the United States (EIA, 2016). Centralized heat pump water heating...

This research project was performed to support the development and implementation of California’s Title 24, Part 6 Building Energy Efficiency Standards (Title 24) by better understanding the impact of installation location and ventilation on consumer integrated heat pump water heaters (HPWH)...

This research was performed to support the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), to better understand the potential energy and cost advantages of dedicated outdoor air systems (DOAS) and variable refrigerant flow systems...
